CONSTRUCTION OF COED TIRES.

Application filed March 5, 1924'. Serial No. 697,099.

This invention relates to the construction of cord. tires, the generalobjectof theinvention being to stretch the fabric to a degree equal tothat to which it. will be sub- 5 jected whenthe inner tube in the.completed tire is properly inflated and to permeate the fabric withrubber so that the cords: are

surrounded by rubber, thus eliminating friction, prevent stretching andrenders peeling ofl of the rubber parts impossible.

Another object of. the invention is to. provide a. pair of flaps at eachedge; of the fabricwhich are adapted to befolded around a. rubber stripto form the beads of the tire.

'Another object of the invention is to provide simple and effectivemeans for stretching the fabric and forming the beads.

This invention also consists in certain other features of constructionand in the combination and. arrangement of the several parts, to behereinafter fullyklescribed, illustrated in the accompanying drawingsand specifically. pointed, out in the appended claims. V

In describing my invention. in detail, refer ence will behad to theaccompanying drawings wherein like characters denote like. orcorresponding parts throughout the several views, and in which Figure 1is a plan view of anapparatus constructed in accordance with this inven-'Figure 2, is a section. on line 2-2 of Figure 4:.

Figure13is a fragmentary View of a por tion of the locking ring. i

In these views, 1 indicates. a supporting member which ismounted upon'a. shaft 2. which issupported by the uprights 3. The member 1 carries-asetof hollow spokes 4E and a second set. of. hollow spokes 5,, the,second set being carried by the slides 6 whichare arranged, to slide inthe member-1 and which. are provided with. arms? which have. nuts 8-thereon which engage the screw threaded. ends of the shafts, 9 rotatablymounted in the supporting member 1; and; which have pinions l0 thereonwhich are adapted to be engaged. by a gear 11 con 79 nected with asliding'sleeve 12 supported by the, shaft 2 and which has a. gear 13thereon adapted to. bemoved into mesh with a gear 1.4011 the powershaft. 1 5 by a. lever. 16. Thus the spokes 5 can be moved longitudinally in the supporting." member when desired. The spokesfformbearings for the. shafts 17 which are provided with threaded heads. 18on their outer ends for. engaging the threaded interiors of the hollowmembers 19 which are adapted to be detachably connected with the core.sections 20 and 21. As shown in F igure 12, the members 19 have theirexteriors of square, shape in cross, setion, and the spokes 4 and 5have. also square exteriors with their interiors circular to; receivethe shaft 17. Beveled gears 22 are placed on the inner ends of theshafts 17 and these gears. on the. shafts in. spokes 4 are adapted toengage the teeth on one-face' of the beveled gear 23 on. the slidingsleeve 24. and the gears 22 on the, shafts in the spokes .5. are adaptedto engage the teeth on one face of the. bevel gear 25 on the slid ingsleeve 26, the. sleeve 24, having av gear 27 on: its. outer end whilethe sleeve 26. has. a gear 28 on its outer end, these gears 27 and2.8being arranged to be moved into'mesh with the gears 29 on the, powershaft 15. by the levers 30 and 31. I g are supported bythe parts.carried by the spokes 4; while the sections 21. are supported by theparts. carried by the spokes. 5 so that these sections 21 canbe. movednot only radially as can the. sections 20 but they can also be movedlongitudinally of the supportingv member 1 and from under the sections.20 so asto ermit these secti'ons20 to be mqved. inwarc 1 2 to their fullextent, The; fi lfitins 21 are. f wedge as w Thecore. sections 20. 9 v

" to fit between the soctions and the ends of the sectionsQl havewedge-shaped pro- 'jections32' thereon for engaging recesses 33 in theends of the sections 20 and all the sections are provided withlongitudinally extending grooves 34 in one side for receiving asectional locking ring 35 for holding curved recess formed in one of thesections Y 20 when the locking ring is given a'partial rotary movement.7 f' locking ri'ngis held in position by'means of a screw 38 passingthrough an ear 39 on the sections together. I

thesections of the ring are held together V by the pins 36 andonesection is. provided The abutting ends of with a curved tongue 37 forengaging a The other sect-ion of the saidsectionand'entering one of thesections 20. v The bead forming flanges 40 are connected lit ,by thebrackets 41 with the interiorly screw threaded members 42 which aresimilar to i V the members 19. 7 These members 4-2 are engage'd' by thethreaded heads of the shafts ed to'mesh with the 43 which are carried inthe bearings 44 sup ported by the slides 45 in the member 1, he slideshaving nut parts 46 thereon which engagethe threaded portions of theshafts 47 mountedjin the member 1 and which have ".pinions 48 attheouter endswhich are adapt- I gear 49 formed with the gearjll andwhich is adapted to be moved into mesh with the gear 50 on the powershaft by'the lever 16. The shafts 43 have the bevel ears 51on theinnerends which are designed to mesh with the teeth on the V 1 outerfaces of the gears 23 and 25 when the levers .30 and 31 are moved toslide the V sleeves '24 and 26 toplace the gears 23 and 25 in mesh withthe gears 51. The levers 16, 3 0 and 31 are held in their adjustedpositions 7 by means of the notches 52, engagingthe keeper bar '53.

The cord fabric is provided with a pair of flaps 54 and 55 at each edgeandthese flaps are foldedabout the strips 56 to form the beads of thetire and apair of rings 57 is placed on the mold to receive the inneredges of the" beads. These rings-cooperate with the bead mol'ds 40 toform the beads and after the parts have been'brought into'mold- 'ingposition they are fastened together by the bolts -58so that thepartially formed tire and l the. mold can be removed from the stretchingv apparatus and the tireffinished in the usua1fmanner. v From theforegoingi't will be seen that by manipulating the levers 16, .30, and31 the sections 21 ca-njbemovedinwardly and then wardly to form thebeads, the locking ring 7 meshes. and when the rubber parts are builtupon it it will become permeated with rub ber. The fabric iswovenseveral sizes sn'1all er than the'regular tire size and it is woven witha larger sized cord at the tread and reduced in size as it meets theside walls. It J is the same at both sides and its edges are providedwith two flaps 101 enclosing thebead forming strips. The cord fabric ispermeated with rubber before it is stretched over the mold. I

t is thought from the foregoing description that the advantages andnovelfeatures of my inventionwill be readily apparent.
